Expiration date of hankook tires

In an indirect measuring system, pressure monitoring is carried out with the help of the vehicle’s ABS sensors. The ABS control unit detects the loss of tire pressure due to a change in rolling circumference. A tire with low air pressure needs to make more turns than one with correct air pressure. However, these systems do not work as accurately as direct measuring systems and, in addition, they need the pressure loss to reach approx. 30% before they can give a warning.     The advantage is their relatively low price, as they can use many of the vehicle’s own components. Only the ABS software and an additional indicator on the dashboard need to be adjusted.

Before changing wheels or tires, it is necessary to consider whether the vehicle has an RDKS. This can be determined, for example, by the presence of a colored valve, a colored valve cover, a symbol on the instrument panel or an additional unit for the indicator (in systems that have been retrofitted). When taking delivery of the vehicle, it is advisable to ask the customer whether the vehicle is equipped with an RDKS and to point out some special features.

➡ The tread depth should be greater than 1.6 mm. The tires are provided with an indicator that indicates this, although with wet ground this minimum may not be sufficient since it would not evacuate the water completely.

Thus, for example, at 120 km/h they wear more than at 90 km/h; if the pressure is low, the casing will deteriorate, there will be a greater heating and also, as there will be a greater rolling resistance, fuel consumption will increase. If the tire pressure is higher than the correct one, there is a high risk of cuts or punctures, and it will also lose adherence.

In addition, if we change only two tires, we must put the new ones on the rear axle, whatever the type of traction our vehicle has. Why? Very simple. Experts advise this for several reasons among them because controlling the rear axle with a flat or blown tire is much more difficult than controlling the front axle where we can help us with the steering.

First of all, be careful with the offers. I’m not saying that you shouldn’t take advantage of them, but you have to be sure to choose tires that are approved for your car in terms of dimensions and characteristics. Besides, now you have a tool, the new identification label, which can guide you at least when comparing one tire with another. Here we tell you how to interpret the label to choose the right tires for your car.  That said, and regardless of the brand of tire you finally choose, you have to take into account several factors not only to avoid problems with the ITV, but also to drive safely and not to condition the functioning of the vehicle’s suspension.  The first thing to do is to review the technical inspection card, which lists the tires approved for your car. If there is only one and there are no alternatives, or if you want to use different sizes from all the options listed in the technical data sheet, you can use another combination of width and profile as long as the final development does not vary by a maximum of 3 percent, and the speed code and load index are equal to or higher than those of the tires approved for your car.
